Can you provide some straightforward instances of single-axis zooming using d3?

I'm interested in creating a single-axis zoom for d3's zoom behavior. Are there any straightforward examples that demonstrate how to achieve this? I came across Mike Bostock's example, but I found it a bit complex to grasp.

Here is the code snippet that I have been working on:

var zoom = d3.behavior.zoom()

svg.call(zoom);

zoom.y(yRange);

Just to clarify, I am specifically aiming to enable the y-axis zoom functionality during the zoom event.

I would greatly appreciate any guidance or resources that could assist me in this task. Thank you in advance.

Answer №1

I implemented a new zoom feature as follows:

function calculate() {

    visualization.select("g.x.axis").invoke(xAxis);
    visualization.select("g.y.axis").invoke(yAxis);


    d3.select(".lineGraph")
        .update("d", lineFunction(lineData));
}

Additionally,

.center([xRange(0), yRange(0)])
    .on("zoom", calculate);

was incorporated into the zoom behavior. Consequently, the y-axis now supports both zooming and dragging functionalities.
